To all whom it may concern."

Be it known that I, CECIL M. CLARKE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Apparatus for Manufacturing Sheathing Material, of which the following is a specification.

My invention relates, more particularly, to apparatus for producing the sheathing material, more commonly used for roofing pur oses and generally termed prepared roo g, which is formed of a base or foundation strip of felt or other suitable, durable and absorbent material, treated to a suitable material for rendering it waterproof and having its upper surface coated with an adhesive substance, such as asphaltum, or the like, and with a surface-coating of granular particles of any suitable material, as for example crushed stone, slate, or other similar material, or sand, or the like, applied to and adhering to the adhesive coating, the

granular particles being providedof different colors or different physical characteristics and applied to such positions on the coating thata design is produced thereon.

My object is to provide an improved apparatus whereby sheathing material of the general character above stated and with the granular coating-particles arranged substantially in the same plane, may be produced economically and rapidly.

Referring to the accompanying drawings, Figure 1 is a diagrammatic view in elevation of my improved apparatus, the parts of the apparatus being of common form and arranged in the same manner, as in apparatus now commonly in use for waterproofing and coating material to produce sheathing material, excepting as regards the device fonapplying to the asphaltum coating the granular surfacing particles; and F 1g. 2, an enlarged plan section, taken at the line 2 on Fig.1 and viewed in the direction of the arrow, this section being taken through the devices for applying the granular particles to the asphaltum coating on the foundation sheet, and showing different portions of the sheet, the separated section of the sheet representing the condition presented by It after the non-adhering particles are removed from the strip.

The general characteristics of myimproved apparatu are the same as those of machines now commonly employed for the production of prepared roofing of the vaable manner.

riety involving the foundation strip and a surfacing of slate, sand, broken stone, or the like, and therefore a diagrammatic representatlon of the apparatus, excepting as to its novel features, will suffice. In the apparatus hown the strip of material, as for example felt, which is to form the foundation strip of the finished sheathing material, is represented at 3 and, in practice, is provided in a roll as at l, the roll being supported to permit the strip to be unwound therefrom, in any suitable manner, as by journaling it on the shaft represented at 5. The strip 3 passes over a roll 6 journaled in any suitable manner, thence downwardly into a tank 7 and under rollers 8 and 9 journaled therein near the bottom of the latter, and upwardly over a heated drive roller 10 journaled in the top of the tank and-driven in any suit- The tank 7, in accordance with common practice, would contain any suitable waterproofing, readily absorbed 11 journaled in any suitable manner and driven in any suitable manner, these rollers serving to remove from the strip 3 the surplus liquidcarried up thereby from the tank. The strip 3 passes beneath a tank 12 which contains any suitable adhesive waterproof coating of relatively thick constitu ency, the material usually employed being asphaltum. The material from the tank 12 discharges upon the upper surface of the strip 3 through a valved outlet 13 which extends across the machine practically throughout the width of the strip 3 and serves to apply thereto a coating of the asphaltum or other material used. F rem this point the strip 3 passes between Sta tionary, heated, squeeze rollers 14 and 15 which operateto spread the asphaltuin supplied to the strip to produce a uniform coating thereon in accordance with common practice. The strip3 then passes under a device constructed in accordance with my invention for applying to the asphaltum coating on the strip 3, particles such as crushed stone, slate, sand or other suitable material, which, preferably, together with other particles afterward applied to the strip, form the surface coating. This device comprises a hopper 16 supported in any uitable. manner'to extend above the strip 3 and of a width substantially equal to the width of the said strip, as shown in Fig. 2. The lower end of this hopper, which is open, is provided with a pair of inwardly extending flanges 17, which reach short of each 5 other as illustrated and which form guides for a pair of edgewise opposed slides 18 and 19 which lie in the same plane and form a bottom for the hopper 16. These slides 18 and 19 are so constructed that by shifting them relative to each other, material from the hopper 16 will be caused to be spread upon the upper, coated, surface of the strip 3, to formv a skeleton design thereon; these slides to serve this purpose being preferably 5 each formed at the edge thereof which opposes the other slide, with a eries of recesses 20.equidistantly spaced apart, so that when the slides 18 and 19 occupy a certain position relative to each other, as illustrated in 20 Fig. 2, the intermediate recesses 20 in the opposed slides will register with each other. Cooperating withthe slides 18 and 19 is mechanism for reciprocating them in opposite directio'ns, the mechanism shown, and which is merely illustrative of one kind of mechanism which may be employed for this purpose, comprising a shaft 21 driven in any suitable manner (not shown), and equipped with a crank pin 22 connected with a rockerarm 23 by a link 24 pivotally connected with the pin 22 and with a pin 25 on the'arm 23, this arm being connected with a shaft 25' supported in journaled position in any suitable way. The arm 23 is provided with extensions 26 and 27 extending at angles thereto and provided with pins 28 and 29, respectively, arranged 'eccentrically of the shaft 25 and at opposite sides thereof, these pins forming pivot connections for pitmen 30 and 9 31 pivotally connected at their other ends to pins 32 and 33 on the ends of the slides 18 and 19, respectively.

It will be understood from the drawing and the foregoing description that when the shaft 21 is rotated the arm 23 is rocked back and forth, thus causing the slides 18 and 19 to be reciprocated in opposite directions. As the strip 3 passes along under the hopper 16, the movement of the slides 18 and 59 19, .as stated, will cause material to discharge from the hopper 16' through the recesses 20 onto the asphaltum coating of the strip 3, to produce the skeleton design substantially as shown in Fig. 2, wherein the bands of surfacing extending obliquely of the strip 3 and in intersecting relation, are

represented at 341, and the sections of asphaltum coating remaining uncovered being represented at 35. r

After passing under the hopper 16 and the operating mechanism therefor, just described, the strip 3 passes beneath a hopper 36 provided with a discharge slot 37 along its lower edge, the hopper 36 extending practically the entire width of the strip 3 and its outlet 37 extending practically throughout the length of the hopper. This hopper is provided for receiving and spreading the particles of granulated material which are to form the surface coating of the finished sheathing material, between the bands 34. The strip 3 in passing under the hopper 36 has spread over its entire surface, the granulated material contained in the hopper 36; and from this hopper the strip 3 passes under and over pressing and drying or cooling rolls 37, 38, 39 and 40, journaled in any 'suitablemanner to rotate. In passing from the roll 37 to the roll 38, all of the non-adhering surfacing material falls from the strip 3; and during the passage of the strip along the rolls 37 to 10, inclusive, the surfacing particles which contact with the asphaltum coating are caused to become partially embedded therein and adhere thereto. While granular material is applied to the strip 3 from the hopper 36 throughout the area of the strip, the material supplied from this hopper does not adhere to the strip, excepting to the sections 35, which are the portions of the coating which are left uncovered upon'applying the material from' the hopper 16 in bands 34, as stated. Thus,

the surface coating of the material being produced is caused to present a design formed of granular particles of different color, or different characteristics as shown at the section'X-of the strip 3, the sections of granular coating thus provided being disposed substantially in the same plane and thus are in the nature of inlays, as distinguished from superposing granular material upon a previously applied coating of granular material of another color or having other characteristics, to form a design.

It will be understood that in accordance with common practice the strip 3 beyond the roller 404s engaged by suitable feed mechanism (not shown) for feeding the strip 3 along the path hereinbefore described to bring it into operative position relative to the various elements of the apparatus hereinbefore explained, and preferably Wind it into a roll.

It will be readily understood from the foregoing that patterns of many different forms may be produced on the coated strip 3. The speed at which the mechanism for reciprocating the slides 18 and 19, operates, relative to the speed at which the strip 3 travels past the hopper 16, determines the angle at which the intersecting bands 34 extend relative to each other and the straightncss of the bands 34: and conse quently the shape of the intermediate sections 35. An intermittent movement of the slides 18 and 19 or variation of length of strike will also serveto 'vary the shape of the design figure produced on the strip 3. In fact, many other different designsmay mariner be produced on the strip 3 by the. substitution for the particular mechanism shown in Fig. 2, of other common and well-known mechanical movements, for controlling the operation of the delivery mechanism of the hopper 16.
